Colorectal Cancer Surgery Bangalore

The most important warning signs are: rectal bleeding or blood visible in the stool; a significant change in bowel habits persisting more than 4 weeks (new constipation, more frequent stools, alternating diarrhoea and constipation); a feeling of incomplete emptying after passing stool (tenesmus); unexplained iron deficiency anaemia (especially in men and post-menopausal women); significant unexplained weight loss; persistent lower abdominal cramping or bloating; and a palpable abdominal or rectal mass. The important thing to understand is that colorectal cancer in its early stages — when it is most curable — causes exactly these symptoms, which are also caused by many benign conditions. The error patients make is attributing these symptoms to piles, IBS, or stress without getting a colonoscopy.

Haemorrhoids (piles) are the most common cause of rectal bleeding in India, and the vast majority of patients with fresh rectal bleeding do have piles. However, colorectal cancer also causes rectal bleeding, and the two can coexist. The problem with attributing all rectal bleeding to piles is that cancer gets delayed by months or years. You need urgent colonoscopy if: you are above 45; the bleeding is mixed with the stool rather than only on tissue paper; you also have changed bowel habits or weight loss; you have iron deficiency anaemia; or the bleeding does not settle after treating piles. A colonoscopy is the only way to be certain. Never treat rectal bleeding with pile creams indefinitely without an endoscopic examination of the bowel.

In most cases, no — bowel is reconnected after the cancer is removed. For colon cancer: standard hemicolectomy removes the affected segment and rejoins the bowel — no stoma needed. For upper and mid rectal cancers: low anterior resection reconnects bowel; a temporary loop ileostomy is sometimes created for 6–12 weeks to allow healing, then reversed. For low rectal cancers very close to the anus: abdominoperineal resection (APR) removes the anal canal and sphincter muscles, requiring a permanent end colostomy. Whether you need a permanent stoma depends on how close your tumour is to the anus and your sphincter function. Discuss this specifically with your surgeon — advances in technique have allowed sphincter preservation in many low rectal cancers that previously required APR.

Total mesorectal excision (TME) is the surgical technique in which the rectum is removed together with its complete surrounding package of tissue — the mesorectum — within an intact fascial plane. This mesorectum contains the lymph nodes and small blood vessels where microscopic cancer spread occurs. Before TME became standard, local recurrence of rectal cancer was 20–40%. With TME, local recurrence is below 5% at specialist centres. It requires specific technical training, precise dissection in an avascular anatomical plane, and is strongly volume- and surgeon-dependent. The quality of TME — measured by the pathologist who examines the specimen — is one of the most important predictors of your long-term outcome. Ask your surgeon specifically about their experience with TME.

It depends on stage and location. For colon cancer: Stage I — surgery alone is curative. Stage II low-risk — surgery alone. Stage II high-risk (T4, perforation, obstruction, poor differentiation) — consider adjuvant CAPOX or FOLFOX chemotherapy. Stage III (lymph node positive) — adjuvant chemotherapy for 6 months is standard. For rectal cancer: locally advanced tumours (T3–T4 or node-positive on staging MRI) receive neoadjuvant long-course chemoradiotherapy (LCRT) or short-course radiotherapy before surgery — this shrinks the tumour, reduces local recurrence, and sometimes allows organ preservation. The treatment plan for every colorectal cancer patient should be discussed in a multidisciplinary team meeting involving surgery, oncology, radiology, and pathology.

For average-risk adults in India: start colonoscopy from age 45, every 10 years if normal (lower than the previous 50-year recommendation, driven by rising CRC in younger adults). Start earlier if: a parent or sibling was diagnosed with CRC or colorectal polyps — start at age 40 or 10 years before their age at diagnosis, whichever is earlier. If you have Lynch syndrome or FAP: start from age 25–30, annually. If you have ulcerative colitis or Crohn's colitis: surveillance colonoscopy from 8–10 years after diagnosis. Colonoscopy is uniquely powerful because it both finds and removes pre-cancerous polyps — turning a potential cancer into a preventable outcome.
